I've used the GVG, but I don't own one myself. (reason for editing the post) Maybe someday I'll buy one, and do a direct comparison.  I also added a question mark to the title because there's really no 'ultimate' way to travel. Just what works for you. If you guys are breaking thru on 25 mg, I may be wasting spice.

Perhaps the water is the issue, I'll give it a try without.
